“…After plant volatiles are collected, they are usually identified with gas chromatography-mass spectrometry (GC-MS) with examples for trap crops including Erigeron annuus (Halloran et al, 2013), Brassica rapa (Thoming et al, 2020), andTrifolium repens (Allsopp et al, 2022). Sunflowers (Helianthus annuus L.: Asteraceae) have been used as trap crops to control yellow peach moth, Conogethes punctiferalis Guenée (Lepidoptera: Crambidae), which is one of the most common fruit borers causing damage to peach, pear, and Chinese chestnut (Deng et al, 2019) in orchards in China (Figure 1; Wan et al, 2016Wan et al, , 2019. Our previous study found that the planting of trap crop sunflowers decreased the abundance of C. punctiferalis populations by 39.4%-48.1% in orchards (Wan et al, 2016).…”

Sunflowers (Helianthus annuus) are potential trap crops to attract the yellow peach moth (Conogethes punctiferalis) in orchards but the volatile compounds released from sunflowers and their effects on C. punctiferalis behaviour are not clear. Here we used solid phase micro‐extraction to collect volatiles released from flower disks of sunflowers, identified them by gas chromatography–mass spectrometry, and examined the attractiveness of some of the compounds to mated female adult C. punctiferalis moths in Y‐tube olfactometer choice tests. We detected nine volatile compounds (α‐Pinene, β‐Phellandrene, Camphene, β‐Pinene, 3‐Carene, D‐Limonene, Eucalyptol, γ‐Terpinen, and Valencene) with consistently large peak areas for α‐Pinene and β‐Phellandrene. Among tested volatiles, both α‐Pinene and β‐Phellandrene were attractive to C. punctiferalis in olfactometer tests but this was only significant for higher concentrations of β‐Phellandrene. This suggests that β‐Phellandrene may promote C. punctiferalis oviposition on sunflower disks. This study provides insights into volatile chemical mediated responses of insect herbivores to trap crops.

The plum fruit moth (PFM), Grapholita funebrana, and the oriental fruit moth (OFM), G. molesta, are closely related fruit moth species that severely damage fruit trees in Rosaceae. Both species share common primary sex pheromone components Z8-12:Ac and E8-12:Ac. The secondary sex pheromone components of PFMs consist of Z8-12:OH, Z8-14:Ac, and Z10-14:Ac, while those of OFMs include Z8-12:OH and 12:OH. Previous researchers have proved that the inclusion of Z8-14:Ac and Z10-14:Ac did not augment PFM catches but inhibited OFM catches in orchards in Europe, thereby maintaining the species-specificity of the PFM sex attractant. However, which of these components, Z8-14:Ac or Z10-14:Ac, plays the major role in inhibiting OFM attraction remains unclear. In the current study, electroantennogram (EAG) assays indicated that both OFM and PFM males exhibited a moderate EAG response to Z8-14:Ac and Z10-14:Ac. Rubber septa loaded with varying ratios of Z8-14:Ac (1% to 30%) or Z10-14:Ac (5% to 110%) combined with a constant dose of Z8-12:Ac and E8-12:Ac produced diverse trapping effects. Sex attractants containing Z8-14:Ac did not significantly affect the trapping of PFM males but drastically reduced the capture of OFM males, with the reduction reaching up to 96.54%. Attractants containing more than 10% of Z10-14:Ac simultaneously reduced the number of OFM and PFM males captured. Z8-14:Ac was indispensable for maintaining the specificity of sex pheromones. Fluorescence competitive binding assays of recombinant GmolPBP2 showed the lowest Ki value (0.66 ± 0.02 μM) among the PBPs/GOBPs from OFMs, suggesting that it is the most likely target for Z8-14:Ac. Molecular dynamic simulation and site-directed mutagenesis assays confirmed that the Phe12 residue, which forms a π–alkyl interaction with Z8-14:Ac, was crucial for GmolPBP2 binding to Z8-14:Ac. In conclusion, Z8-14:Ac is vital to the specificity of PFM sex pheromones inhibiting OFM attractants when added to Z8-12:Ac and E8-12:Ac. This could be potentially used to develop species-specific sex attractants for the PFM.
